 Forcing Notrump

 

 

Chapter III Responder’s Rebids

 

§4.Opener Rebids 2♠ after a 1 opening bid: 1-1NT; 2♠.

Minimum of six hearts and five spades; 15+ HCP; game forcing

 

Rationale for the 6-5 major minimum: Responder denied a four or more card spade suit by responding 1NT. Thus, there is little need for Opener to show a four card spade suit and the guarantee of a five card spade suit facilitates the auction after the reverse.

2NT by Responder:1-1NT; 2♠-2NT. An artificial systemic response indicating a minimum hand (approximately 6 to 8 HCP). It denies a two card heart fit, and it denies a three card spade fit. It also denies a side seven or more card minor.

Opener’s rebids:

a) Holding 2-0 in the minors, if Opener wishes to make a slam try, she bids her two card minor at the three level over Responder’s 2NT response: 1-1NT; 2♠-2NT; 3♣/3. Game forcing.

b) With a game going hand but no slam interest: Opener jump rebids 4. Nonforcing. Responder either passes or corrects to 4♠ (signoff).

Three of a minor by Responder:1-1NT; 2♠-3♣/3. Seven or more card suit. 9 to 11 HCP. Denies two or more hearts. Denies three or more spades. Forcing to four of Responder’s minor by either Opener or Responder.

Opener’s rebids holding a two card fit for Responder’s minor:

a) With a minimum: Opener raises Responder’s minor to the four level: 1-1NT; 2♠-3♣/3; 4♣/4. Game invitational.

b) With extra values: Opener raises Responder’s minor to the five level: 1-1NT; 2♠-3♣/3; 5♣/5. Signoff.

c) With slam interest: Opener cue bids her void in the other minor: 1♥-1NT; 2♠-3♣; 3. Forcing to game in Responder’s minor. Slam invitational.

Opener’s rebids holding fewer than two cards in Responder’s minor

Opener rebids 3♥, forcing to 3NT, four of Responder’s minor, or game in one of Opener’s majors.

Responder’s rebids over 3 by Opener (1-1NT; 2♠-3♣/ 3; 3):

– With two or fewer spades and one heart: Responder raises to 4. Signoff.

– With two spades and zero hearts: Responder bids 3♠. Forcing.

– With one or zero spades and zero hearts: Responder rebids her seven card minor at the four level: 1-1NT; 2♠-3♣/3; 3-4♣/4. Nonforcing.

 

3 by Responder: 1♥-1NT; 2♠-3. Shows two or three hearts. Does not deny three spades. Game forcing.

Responder’s heart raise shows a non-constructive single raise, with three card heart fit and 6 to 7 PSP, or a preference with two hearts and good 8 to 14 HCP.

Opener’s rebids:

a) With a minimum (15 to 17 HCP), Opener bids 4♥. Nonforcing.

b) With extra values (18+ HCP), Opener cue bids up-the-line (game forcing, slam invitational), bids 4NT, RKCB, or bids Exclusion RKCB in hearts, depending on her strength, distribution, and controls: 1-1NT; 2♠-3♥; 3♠/4♣/4/4NT/5♣/5.

 

3 ♠ by Responder: 1-1NT-2 ♠-3 ♠. Shows three spades. Denies two or more hearts. 8 to 10 PSP. Game forcing.

Note: Responder’s original 1NT response denied four or more spades.

Opener’s rebids: Same as after a 3 rebid by Responder (see “3 by Responder” immediately above).

 

3NT by Responder:1-1NT; 2♠-3NT. 9 to 12 HCP. Denies two or more hearts. Denies three or more spades. Shows length and strength in both minors. Nonforcing.

Opener’s rebids . Typically, Opener passes: 1-1NT; 2♠-3NT; Pass. Rationale: the misfit indicates slam is unlikely; however, if Opener has great strength (18+ HCP), she makes a quantitative raise to 4NT. Nonforcing. Slam invitational.

 

4♣ (or 4) by Responder: 1-1NT; 2♠-4♣/4. Splinter (singleton or void) in clubs (diamonds) in support of hearts. 8 to 9 HCP. Three hearts. Game forcing.

Opener’s rebids: depending on her strength and distribution, Opener either signs off in 4, cue bids up-the-line, or bids 4NT, 1430 RKCB in hearts.

 

4 by Responder: 1-1NT; 2♠-4. Delayed three card limit raise. 10 to 12 PSP. Nonforcing. Slam invitational.

Opener’s rebids: depending on her strength and distribution, Opener either passes 4, cue bids up-the-line, or bids 4NT, 1430 RKCB in hearts.

 

4♠ by Responder: 1-1NT; 2♠-4♠. Three card limit raise. 10 to 12 PSP. Nonforcing. Slam invitational.

Opener’s rebids: depending on her strength and distribution, Opener either passes 4♠, cue bids up-the-line, or bids 4NT, 1430 RKCB in hearts.

 

4NT by Responder: 1-1NT; 2♠-4NT. 1430 RKCB in spades (the last naturally bid suit).

Balanced 18 to 19 HCP; typically, 5-3-3-2; occasionally, 5-4-2-2; highly game invitational

 

 Pass by Responder: 6 to a bad 7 HCP. Denies a three or more card fit for Opener’s major.

Three of a minor by Responder: 1/1♠-1NT; 2NT-3♣/3. Six or more card minor. suit. 6 to 11 HCP. Denies three or more card fit for Opener’s major. Indicates highly distributional hand. Game forcing. May have slam interest.

Three of Opener’s major by Responder: 1♥-1NT; 2NT-3. A non-constructive single raise. 6 to 7 PSP. Three card support for Opener’s major. Highly game invitational.
